Objectives:1. Describe Epidemiology, Diagnosis,Pathophysiology, and Treatment ofRosacea and Ocular Rosacea2. Discuss Recent Research Finding ofRosacea and Ocular Rosacea3. Discuss Ocular Rosaceas Relationshipto other Angiogenesis Based Diseases
Outline:1. Case Presentations2. Diagnosis and Details3. Observations & Collaborations4. A Hidden Concern
A Definition of RosaceaRosacea is a multifactorial, hyper-reactivity, vascular andneural based disease with a broad range of facial andmanifestations where normal vasodilation is greater andmore persistent and involves an autoimmune componentwhere microscopic amounts of extravasated plasma inducelocalized dermal inflammation where repeated externaltriggers lead vasodilation, telangiectasias, redness witheventual fibrosis and hypertrophic scarring of the dermis.
Years of Observations of Ocular Rosacea 1. If also had diabetes, tended to develop proliferative diabetic retinopathy 2. If they also had age related macular degeneration (ARMD), tended to develop wet ARMD 3. If they had a corneal transplant, they would tend to have a rejection more often.
Doxycycline Magical Properties:1. Anti-Angiogenic at low doses2. Anti-bacterial at higher doses

More Complete Definition of RosaceaRosacea is a multifactorial, hyper-reactivity, vascular andneural based disease with a broad range of facial andocular manifestations where normal vasodilation is greaterand more persistent and involves an autoimmunecomponent where microscopic amounts of extravasatedplasma induce localized dermal and meibomian glandinflammation and where repeated external triggers lead toangiogenesis (the recruitment of new blood vessels),vasodilation, teleangiectasias, redness with eventualfibrosis and hypertrophic scarring of the dermis andmeibomian glands.Likely a central underlying factor in all subtypes of rosacea,particularly ocular rosacea, involves VEGF and similarangiogenic factors.
Future Research For Ocular Rosacea 1. Is Severe Ocular Rosacea due to increased angiogenesis activity at the lid margin? 2. Would they benefit from topical anti- angiogenic medications?
Future Research For Ocular Rosacea 1. Do severe ocular rosacea patients have an increased risk of systemic angiogenesis? 2. Do these patients need to be evaluated for an increased risk of internal tumors or metastasis if primary tumors present?
Recommendations for Ocular Rosacea Patients:1. Avoid inflammatory factors (triggers, sun, smoke)2. Eat antioxidants, Omega 3s,2. If must treat with doxycycline, use lowest doseStart with 20mg q day; 40-mg, controlled release formulationof doxycycline monohydrate is an anti-inflammatory drug3. General medical check ups
